I’m also hoping things will happen quickly. But I’m hearing that LH351D may be delayed longer than expected, because they were apparently not ordered back in December when I thought they were. And it sounds like there’s some sort of difficulty in getting them. So I’m kind of wondering if it would make more sense to use SST-20 instead.

I know it has come up before, which is why I mention it, but what do people think of the idea?

Here’s a very brief summary of the biggest differences:

LH351D has a wider, flatter, floodier beam. Probably more lumens.

SST-20 has a narrower, throwier beam. Illuminates farther away.

Both can still have hit-or-miss tints depending on the exact bin used.

To be clear, XP-L HI 3D is still a “yes”. If I understand correctly, XP-L HI should be able to go to production as soon as the driver fit issue is worked out. The question is only about the LH351D version.

I would, of course, want the XP-L version as soon as it can be done. Next, i would say do the SST-20, if it can be done sooner. Then, do the LH351D, when the good tint emitters are available. I think a lot of people would really like the SST-20, and probably plan to make that swap anyway. I would personally get one of all three, and then a second one of whichever I like best.

As said above, there isn’t really going to a throw/flood option, they are all “floody”. I think the SST-20 would be a great option. I honestly might even prefer it to the LD, depending on how much lumen difference there will be.

After hearing your comments on LH351D’s beam profile in a TIR triple/quad, and now seeing plenty of beamshots of them… SST-20 all the way.

If people want more flood a wider TIR optic is easily available, or they can just use DC Fix/scotch tape like many of us do for lights already.

It’s all a matter of personal taste. But I find that LH351D is just a bit too floody for me. I much prefer the extra punch of XPL HI or SST 20.

I expect when I get my FW3A I’ll probably swap out the emitters for XPL HI (probably two 5000K and one 4000K) and the optic to 10507.

SST 20 is nice, but I find it looks a bit too green-tinged. Also compared to XPL HI, SST 20 with its lower Vf it draws more current which causes the head to heat up faster resulting in the driver ramping down output faster.
